Here's my how to video on doing a lawn mower oil change. Its not rocket science, its actually pretty easy, AND it will extend the life of your mower. Ready? Watch the video and scroll through the instructions below:
Lawn Mower Oil Change, Step By Step
Check the manual to see what kind of oil your engine uses. Most use 30W, but just check, OK? By changing the oil, you are already helping the engine last much longer. Do a lawn mower oil change a few times a year and your mower could last forever, mbe!
Run the mower to warm up the engine. This gets the oil hot and the debris that settles up and moving. Turn off the mower.
Place plastic food wrap over the gas tank fill and screw the cap down. Not so tight that you can't get it off again, but snug. Now we are going to gently turn the mower on its side. Position a plastic tub such that when you tilt the mower on its side, the oil fill tube will pour into the tub.
If your mower has an oil drain plug instead of a fill tube, you will have to tilt the mower on its side, remove that plug, then place the mower over the bucket. This may take some finesse and a friend to help.
Be sure to tilt the mower so that the gas cap is on the higher side of the mower, so no gas could leak out if the cap leaked. Tilt the mower into the bucket and let it sit while the oil drains out. You can prop up the mower and let it sit for a while.
Get your fresh oil ready and a funnel. You can make funnel out of a piece of paper if need be. Tilt the mower back onto its wheels, and slowly add the new oil into the oil fill tube. Use the dipstick to make sure there is just enough oil.
Do Not Over Fill The Oil. Bad things can happen.
AND recycle the used oil. Take it to a quick lube shop or a car repair shop, they will recycle the oil. Don't dump it in the woods or a stream, OK?
This same process can be used for your generator oil change or your riding mower.
